Something I've wanted to try for some time, but didn't have a probe (that didn't rely on metal conductivity) to do it.  Niche trick, but might come in handy later!

CNC Surface Mapping... ON EARTH!

ADVENTURES! in surface height mapping and CNC. I think this is sometimes called surface digitizing, but I can see this coming in real handy for non-critical machining work such as engraving, perhaps. ----- thumbnail background: Nadjib BR / Unsplash.

Ohh boy 🥰

Are you interested in selling that engraved block? Would look really good in my china cabinet. I know the wife would love it.

You can't post now, I'm at the cinema. 😠

Loved the idea at the end. One could do all sorts of cool stuff with that!

The map includes some error from the probe contacting a sloped surface off-center. You need to take the probe radius into account when computing the reverse map. I'm sure it's a small enough error that it won't matter when gluing wood, but it might make a difference in high accuracy situations.

Now you should have gone back in time and put a stop block in 🤣

Hmm... applications...? Personalized baked potatoes! My fortune us as good as made!
